CTX is collapsing fast, page-16

Great post Mad.
If only more short blasting, manipulation whistleblowing, tick watching investors speculators would take heed - perhaps when I browse HC I would have a far happier right pointer finger, which would no doubt have an easier job without having to scroll through pages of backslapping and group-winging over the 'big-boys' who are ever conspiring to steal the average punters last remaining dollar.

As someone who likes to learn about concepts which are initially foreign to myself, I was intrigued by the following two points:

"- Some investors (foreign or domestic) have taken out derivative positions in order to arbitrage the capital loss that arise from the buyback, and/or

- Some foreign investors who don't benefit from franking credits have taken out derivative positions to arbitrage the franking credits that arise from the buyback,"

While I could make some attempts that may come close to being partially correct for the above scenarios, I am unable to simply and clearly articulate examples - which clearly shows my lack of complete understanding.
Would you mind exploring these two points a little further?
